I am about the farthest thing from an electrical engineer or electrician or anyone else who knows about this stuff. That said, isn't the power in Kw of an outlet just volts*amps? And, if that's right, wouldn't a 240v*50A=12000w or 12Kw?
If I'm correct then twin chargers would give a slightly higher charge from a 240v, 50A than would single chargers?
Please, someone correct me here. Also, I apologize profusely, and prostrate myself before the Internet Gods, if this same exact question has been asked and answered here.
